CARRIER FOR BRAIDING-MACHINES.

Application filed September 5, 1914.

To all whom it may concern Be it known that I, GEORGE F. MQCAHEY, a citizen of the United States, and resident of Providence, in the county of Providence and State of Rhode Island, have invented certain .new and useful Improvements in Carriers for Braiding-Machines, of which the following is a specification.

This invention relates to improvements 111 carriers for braiding machines and has for its object to provide, an improved top weight having an elongated spring tongue which lends to its carrier many advantages over those employing the old style top weight.

It is found in practice that when the old style top weight becomes slightly worn it leans forward when raised and readily passes by the lip on the standard and is thrown ofl", thereby necessitating the reduction of speed of the braiding machine. My improved construction of top weight having a spring tongue entirely obviates this difficulty or fault as the tongue is obliged to yield or bend in passing the weight into position on the standard, andwhen the tongue returns to normal it holds the weight straight and prevents it from tipping forward and, therefore, it cannot be inadvertently thrown from the standard even when the carrier is run at a very high rate of speed.

A further object of the invention is to form the tongue integral with the body of the weight, as it is found in practice that when any spring or other device is formed separate, and attached to the weight by rivets, solder or other fastening, the constant jarring or hammering of the bottom weight against the top soon loosens the fastening, then again, by formingthe tongue integral with the weight the cost of construction is reduced to the minimum.

The invention further consists in causing the tongue portion to extend some distance up into the body of the weight and so increase its operating length, rendering it more resilient and capable of greater yieldability.

A still further object of the invention is to form the whole weight of bendable material so as to provide a natural spring to the tongue, and also to permit the body of the weight to be bent or closed somewhat about the standard to take up slaclmess due to wear.

With these and other objects in view, the

Specification of Letters Patent.

Serial No. 860,333.

invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a side elevation of the carrier showing my improved top weight on the carrier standard. Fig. 2 shows the upper portion of the standard and my improved top weight in section with the spring tongue bent in the act of positioning the weight on the standard. Fig. 3 is a perspective view of my improved top weight.

Referring to the drawings 10 designates the frame of the usual carrier provided with a groove 11 and adapted to run in the usual race-way and 12 designates the spindle of the carrier on which the spool or bobbin 13 is supported. On the standard lat are mounted both the bottom weight 15 and the top weight 16, the upper end of the standard being formed narrower at 17 than the rest of its body portion to permit the enter-. ing of the top weight thereon, and a forwardly extending lip 18 is also formed on the standard above the narrow portion which is designed to serve as an abutment against which the top weight should bring up when raised rapidly to release the yarn, by a quick upward movement of the bottom weight.

It is found in practice in the operation of carriers using the ordinary top weight that after the standard and the top weight have become slightly worn that as the weight is moved upward to the reduced portion 17 of the standard the over-hanging pawl 19 of the weight tends to tip the same forward and when the weight becomes too loose on the standard its forward tipping carries it clear of this lip 18 and it is thrown from the standard. When this happens the whole machine must be stopped to replace the top weight or supply a new one and often necessitates the reduction of the operating speed of the machine. To correct this fault, I have constructed a top weight which cannot be thrown from the standard, the same comprising a body portion 16 to slide vertically on the standard on which I have formed a tongue 20 integral with the body and extending slightly below the bottom edge of the same. In order to increase the operating length of this tongue and render it more resilient, springy and bendable, I have cut or otherwise formed slots 21 and 22 up from its lower edge into the body at either side of the tongue thereby increasing its working length.

By this construction it will be seen as illustrated in Fig. 2 that the weight can only be passed over the lip 18 on to the standard by causing this tongue to bend slightly outward as illustrated in Fig. 2 and as soon as the weight has been positioned the tongue springs back to normal and assists in guiding the wei ht on the standard preventing it from tipping forward, and so eii'ectually obviates any possibility of its being accidentally thrown from the standard even when running at the highest rate of speed.

Another feature of my invention is that I'preferably form this weight of a bendable material such as steel, malleable iron or the like whereby the tongue when formed has an inherent resiliency or spring and the body of the weight is adapted to be closed slightly about the standard to compensate for wear and better fit the same.

It is found in practice that where a spring or other device is formed separate and at tached to the top weight by rivets, solder or other fastening, that the hammering eiiect of the lower weight against the upper, soon shakes the separate piece loose and that the only practical Way of providing a top weight with a tongue is to form the tongue integral therewith.

My improved weight is extremely practical in construction and effective in its operation.

I claim:

1. A top Weight for braider carriers, comprising a body portion adapted to slide vertically on the carrier standard, said body having an integral resilient standard engaging and guiding tongue adapted to yield to permit the positioning of the weight onto the standard.

2. A top weight for braider carriers, com-- prising a body portion adapted to slide vertically on the carrier standard, said body having an integral resilient standard engaging and guiding tongue extending beyond the lower edge of the body portion.

3. A top Weight for braider carriers, comprising a body portion adapted to slide Verti'cally on the carrier standard, a resilient tongue formed from a portion of the body and extending below the lower edge thereof adapted to engage the standard and guide the vertical movement of said weight.

4?. A top weight for braider carriers, comprising a body portion constructed of bendable material and adapted to slide vertically on the carrier standard, said body having an integral resilient guiding tongue extending beyond the lower edge of the body por tion, said tongue being adapted to yield to permit the positioning of the weight onto the standard.

In testimony whereof I affix my signature in presence of two witnesses.
